Storyline: Cardinals are being proclaimed the most pleasant surprise of the early NFL season. With a stingy, playmaking defense and a game-changing receiver in Larry Fitzgerald, they look like a title contender. Rams have been surprising as well, with a vastly improved defense that already has eight interceptions, an efficient offense and respected coach in Jeff Fisher.

Did you know? Cardinals are 4-0 for the first time since 1974, when they were playing in St. Louis.
